In the debate on the Native Authority (Amendment) Law of 1955, the late Premier of the North, Sir Ahmadu Bello, Sardauna of Sokoto, replying to the demand that ‘it is high time in the development of local government systems in this Region that obsolete and undemocratic ways of appointing Emirs’ Councils should close’, commented that ‘the right traditions that we have gone away from are the cutting off of the hands of thieves, and that has caused a lot of thieving in this country. Why should we not be cutting (off) the hands of thieves in order to reduce thieving? That is logical and it is lawful in our tradition and custom here.’ This could be read as a defence against social change, a recrudescence of ‘barbarism’ after the inroads of pax Britannica, and a plea for the retention of the status quo and the entrenched privilege of the political elite.

The analysis of the unban road traffic state based on kinds of floating car data, is based on the model and algorithm of floating car data preprocessing and map matching, etc. Firstly, according to the characteristics of the different types of urban road, the urban road section division has been carried on the elaboration and optimization. And this paper introduces the method of calculating the section average speed with single floating car data, also applies the dynamic consolidation of sections to estimate the section average velocity.Then the minimum sample size of floating car data is studied, and section average velocity estimation model based on single type of floating car data in the different case of floating car data sample sizes has been built. Finally, the section average speed of floating car in different types is fitted to the section average car speed by the least square method, using section average speed as the judgment standard, the grade division standard of urban road traffic state is established to obtain the information of road traffic state.

Abstract Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports. Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well. Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.

Fire Accident

Urban road tunnels are a reasonable remedy for inconvenience due to congested road traffic. However, they bring specific threats, especially those related to the possibility of fire outbreak. This work is a case study for selected urban road tunnels. Considering tunnel specificity, road traffic intensity, and structure and based on the literature data for vehicle fire probability, the chances of a fire accident were estimated for selected tunnels in Poland. It was shown that low power tunnel fires could be expected in the 10–20-year time horizon. Although such threats cannot be disregarded, tunnel systems are designed to cope with them. The chances of a disastrous fire accident were estimated as well. Such events can occur when an HGV with flammable goods or a tanker are involved. Such accidents are fortunately very rare, but, on the other hand, that is the reason why the available data are scanty and burdened with high uncertainty. Therefore, a discussion on the reliability of the obtained results is also provided.
